Our verification notes

Architect rather than contractor - the firm that writes the specification a mason then builds to. Four of its staff appear on the state DHPA roster with Section 106 and tax-credit service codes, which matters if the church is listed or is pursuing historic tax credits. Google Business Profile exists but carries no rating, recorded as empty rather than invented.
